Parker 48F-12-MI27 Brass Iso Port Adapter 3/4 X M27x2

Product Description

The PARKER 48F-12-MI27 is a brass ISO port adapter designed to transition between a 3/4 inch flare connection and an M27x2 metric thread port. Rated to 550 psi working pressure, it is built for hydraulic and fluid power applications where a reliable flare-to-metric interface is required. Constructed from brass, it offers good corrosion resistance across a wide service temperature range, down to -65 degrees F. This fitting is compliant with ISO 6149-3 and SAE 2244-3 standards. It is typically installed by hydraulic technicians, plumbers, and mechanical contractors working on fluid conveyance systems requiring metric port connections.

This adapter is suited for use in hydraulic circuits, fluid power systems, and industrial plumbing applications where equipment uses ISO metric threaded ports. The flare end connects to standard SAE flare tubing or assemblies, while the M27x2 metric end seats into ISO-standard port bosses. It is appropriate for both original equipment assembly and field repair or retrofit work on systems requiring a 3/4 inch flare to M27x2 metric conversion.

Key Features

• 550 psi maximum working pressure for hydraulic and fluid power service
• Flare x metric adapter configuration — 3/4 inch flare to M27x2 metric thread
• Brass construction for corrosion resistance and reliable sealing
• Viton seal material for compatibility with a broad range of hydraulic fluids
• Rated for service down to -65 degrees F
• Meets ISO 6149-3 and SAE 2244-3 standards

Compatibility

Designed as an OEM-style replacement or field-service adapter for hydraulic and fluid power systems using ISO 6149-3 metric port bosses and SAE flare tube connections in the 3/4 inch size range.

Installation Notes

Installation should be performed by a qualified hydraulic technician or licensed mechanic. Depressurize and isolate the system completely before removing or installing any fittings. Use appropriate wrenching flats — do not grip on the hex faces in a way that risks distorting the sealing surfaces. Torque to the equipment manufacturer's specification for the M27x2 port boss; do not over-tighten brass fittings.
